Double Suction Sea Water Transfer Pump

Introduction

The double suction sea water transfer pump has a large delivery capacity and a large corresponding delivery flow, and the double suction split pump just meets its needs. TDSF high-efficiency single-stage double suction split sea water pump is a new generation of series products developed through development and innovation on the basis of our traditional products, with a wide range of performance and the ability of multiple uses. TDSF pump adopts double volute design, and the pump body and pump cover are equipped with stiffeners. The pump shell has high strength, wear resistance and corrosion resistance. It is mainly suitable for conveying clean water and water in waterworks, air conditioning circulating water, heating pipe network system, building water supply, irrigation, drainage pump stations, iron and steel, power plants, industrial water supply systems, fire protection systems, shipbuilding industry, mine water supply and drainage and other occasions for conveying liquid Industrial water, river water, sea water, salt water, pulp water, etc.

● High efficiency:

The best hydraulic model at home and abroad is introduced, and the CFD computational fluid dynamics analysis method is used to optimize and improve; The performance index exceeds the industry level, reaches the advanced level, and the maximum efficiency exceeds 92 percent .

● Low pulsation:

The staggered arrangement structure of two half impeller blades is adopted, so as to change the blade frequency (the frequency of the blade passing through the tongue separation of the pump body), reduce the liquid flow pulse (about 1 percent 4 percent o of the head), make the liquid flow more stable, have higher efficiency, less vibration and more stable and reliable operation.

● Low NPSH:

The shape of the blade inlet edge adopts convex arc optimization design, which increases the flow area of the liquid flow inlet, reduces the inlet flow rate, increases the pressure at the inlet edge, and improves the NPSH.

The airfoil streamline design is adopted at the blade head to reduce the liquid flow impact loss and vortex, which not only improves the maximum efficiency value, but also makes the high efficiency area wider, the pressure distribution uniform and the cavitation performance better.

● High reliability:

The high lift pump adopts double volute design, the double suction sea water transfer pump body and pump cover are provided with stiffeners, and the structure is optimized by ANSYS mechanical analysis software. The pump shell has high strength, and the hydrostatic test of the pump shell is carried out in strict accordance with the hydrostatic test standard in GB / t5656 centrifugal pump class II technical conditions.

The bearing span is short and the shaft is thickened, which makes the rotor less disturbance, stable and reliable.

All impellers shall be subject to level 6.3 static balance test, and the whole rotor shall be subject to level 2.5 dynamic balance test according to API610 standard.

The main shaft adopts the full sealing design without contacting liquid, and the bearing parts are equipped with lip oil seal plus V-shaped sealing ring combined sealing structure, which has excellent oil leakage, dust, water and moisture prevention functions.
